Prepare the marinade. Combine the olive oil, white wine, lemon juice, minced garlic, and Greek seasoning in a bowl or large zip-top bag.
⅓ cup olive oil, ¼ cup white wine, 2 Tablespoons fresh lemon juice, 4 cloves garlic, 2 Tablespoons Greek Seasoning
Marinate the chicken. Add the chicken to the marinade, ensuring all pieces are well coated. Seal the bag or cover the bowl and refrigerate for 4-8 hours. I like to go overnight so the flavors fully penetrate the meat, but you want to go for at least 4 hours.

Preheat the grill. Set your grill up for 2-zone cooking with an overall temperature of 375 degrees F. You'll want one side for indirect heat and one side for direct heat.
Cook over indirect heat. Remove the chicken from the marinade and wipe off any excess liquid with a paper towel. Place the chicken on the indirect heat side of the grill and close the lid. Cook for 10-15 minutes, flipping once in between. You’re looking for the internal temperature of the chicken to reach 145 degrees F with a meat thermometer.
Finish over direct heat. Move the chicken to the direct heat side of the grill and cook for 2-4 minutes per side to get a nice sear. Once your chicken reaches an internal temperature of 165 degrees F (175 degrees F for thighs), transfer it to a cutting board.
Rest and serve. Allow the chicken to rest for 5-10 minutes before slicing. Serve with your favorite Mediterranean sides like tzatziki sauce and grilled veggies, or serve with warm pitas for chicken gyros.
